# Authentication

> Authenticate with Salesforge API and multichannel sequencing endpoints before using the endpoint reference.

Use this page as the authentication entry point before working through the Salesforge API endpoint reference.

Salesforge public API endpoints and multichannel sequencing endpoints in this section use the shared Forge authentication pattern.

Send your API key in the Authorization header as a bearer token.

```http theme={null}
Authorization: Bearer YOUR_API_KEY
```

For the complete cross-product authentication guide, see [Authentication](/authentication).

## How authentication applies here

Use the same auth model for both endpoint groups in this section:

* **Salesforge endpoints** use a Salesforge API key in the bearer header.
* **Multichannel sequencing endpoints** surfaced here follow the same bearer API key pattern for authenticated access.

## Before using the endpoint reference

1. Generate the correct API key for the workspace or product context you are integrating.
2. Send that key in the Authorization bearer header on every request.
3. Review [Security best practices](/authentication/security-best-practices) before using the interactive reference or production integrations.
